java - Android HttpUrlConnection passing header params -

i searched other topics , there answers didn't succeed solve problem. have code , want add together "referer" http headers. after using setrequestproperty method, log results in logcat don't see referer in output. doing wrong?

url url = new url(uri); httpurlconnection con = (httpurlconnection) url.openconnection(); con.setrequestproperty("referer", "http://www.example.com"); for(int i=0;con.getheaderfieldkey(i)!=null;i++){ string headername = con.getheaderfieldkey(i); string headervalue = con.getheaderfield(i); log.d("header", headername + ": " + headervalue); }

i have code not working either:

url url = new url(uri); httpurlconnection con = (httpurlconnection) url.openconnection(); string irnic = cookies.get("irnic"); string routeid = cookies.get("routeid"); string mycookies = "irnic="+irnic+"; routeid="+routeid; con.setrequestproperty("cookie", mycookies); for(int i=0;con.getheaderfieldkey(i)!=null;i++){ string headername = con.getheaderfieldkey(i); string headervalue = con.getheaderfield(i); log.d("header", headername + ": " + headervalue); }

for first code, don't see referer in output , sec code, don't see cookies too. seems setrequestproperty not working! in advance.

edit: can see headers in output not ones added via setrequestproperty method. if code working.

from docs:

getheaderfields

returns unmodifiable map of response-header fields , values

setrequestproperty

sets value of specified request header field.

request not same response. that's why headers different. request have right headers using setrequestproperty
